An acid-base buffer is able to resist changes in pH due to the addition of small amounts of strong acid or base to the system. An acid-base buffer typically contains a weak acid and its conjugate base. 1st attempt Part 1 (1 point) X Feedback See Hir A buffer is prepared by mixing 47.2 mL of 0.183 M NaOH with 125.7 mL of 0.231 Macetic acid. What is the pH of this buffer? (The pk for acetic acid is 4.75.) * 4.22 Part 2 (1 point) X Feedback See Hit Calculate the pH of this buffer after the addition of 0.166 g of solid NaOH. x 0.53
